Folder view cannot display

Hi.

Short time ago, SmartFTP saids "Out of memory" on starting.
Then, no pane displays in workspace.
I can connect to host, but I cannot display Folder View(by View -> Panes -> Folder View).
I uninstall SmartFTP, install again, and reboot PC.
The pane not displays...

Can anyone help me???

Windows XP sp2, SmartFTP v3.0.1017.1

I'm sorry my poor English.
Thanks.

Delete the registry key at:
HKEY_CURRENT_USER\Software\SmartFTP

using regedit.exe

Regards,
Mat
